Description : This study presents a general modelling of drying phenomena to cover a wide range of convective hot air dryers and products, in very different configurations

The aim of this modelling work is to make the energy optimisation solutions proposed for convective dryers more reliable in the context of audits: for example, to analyse the impact of air recycling in the dryer on the drying quality of the manufactured product

This modelling has two components:

1. Modelling of the product behaviour during dryin.
2. Modelling of the dryer and the air movements around the product.

The study identified and generalized a large number of existing models to take into account a wide product typology, including clay, wood, grains, fruits, vegetables, etc.

Description : This study takes interest in a key component of most heat recovery solutions : heat eachangers. The technologies in play, the geometries and fluids can vary tremendously depending on the applications.

In the first part of the study, the different heat exchanger technologies applicable for the recovery of energy from hot effluents discharged from industrial furnaces and dryers in the agri-food, metallurgy and glass industries are identified. Then are adressed the issue of fouling and the prevention and remediation methods proposed to avoid or diminish it. Finally, the feasability of 5 heat recovery cases are studied (4 in agri-food, 1 in glass) : identification of the optimal technology, adaptation measures to the nature of the effluent in order to prevent fouling, evaluation of the gross return on investment.

Description : For purposes of a competititive and energy efficient industrial development, attention has recently been brought to the improvment of industrial air conditionnig and cooling systems.
Compression-expansion cycles have reached acceptable performances, but are challenged by the evolutions in regulation of use of liquid refrigerents (GWP : Global Warming Potential ; ODP : Ozone Depletion Potential). Therefore, the need to reach a durable, competitive and energy efficient production of cold has become a major challenge in industry.

This study presents a overview of recent cooling technologies, aiming to respect the new environmental regulations while maintaining/improving performances.

Description : In France, the amount of heat loss in industrial processes is estimated at 109.5 TWh, wich is equivalent to 36% of the fuel consumption of the industry. Among these losses, 52,9 TWh are exhausted at temperatures exceeding 100°C. Half of the "heat deposit" is produced by agri-food and chemistry industries. Moreover, steams from dryers and fumes from furnaces represent respectively 30% and 38% of available exhausts.

This study targets these two industrial sectors in order to identify the constraints and technologies available to recover the heat carried by industrial steams and fumes. It also aims at highlighting opportunities for new heat recovery projects in the future.

Description : Digital technologies are opening numerous possibilities to improve industrial competitiveness, espectially for energy efficiency. Among these solutions, the implementation of Energy Management Systems (EMS) seems very promising, as numerous players arise on the french market and data management skills become more and more generalised.

Energy Management Systems (EMS) are becoming a key tool for energy management in industry. This study aims at providing a definition of an EMS, mapping the various solutions available on the market and outlining the services provided to industrial operators by these solutions.

Description : The challenge of electrical energy storage must be met to overcome certain energy transition constraints, in particular those linked to intermittent energies. This technology can become essential for manufacturers to optimize their consumption according to network supply (and therefore prices), to load shed at the request of TSOs or, more directly, to integrate and manage renewable energy within their plants.
